drm/panel: simple: add Waveshare LCD panels

Waveshare have a serie of DSI panel kits with the DPI or LVDS panel
being attached to the DSI2DPI or DSI2LVDS bridge. The commit
46be11b678e0 ("drm/panel: simple: Add Waveshare 13.3" panel support")
added definitions for one of those panels, describe the rest of them.

Note, since the panels are hidden behind the bridges which are not being
programmed by the kernel, I could not confirm the pixel format for the
panels.
